What Do I Need To Do To Prepare For My Bladder Ultrasound
Bladder ultrasound preparation is extremely minimal. Your ultrasound technician will let you know whether you need a full or empty bladder during your test. If you need to have a full bladder your doctor may ask you to drink many glasses of water before the test. If your bladder needs to be empty your ultrasound technician will simply ask you to use the restroom before your exam. If you have trouble keeping your bladder full, you may be asked to empty your bladder about an hour before your exam and then drink water once you get to the radiologists office so that the test can be done immediately after your bladder is filled. Therefore allowing you to not have to hold your urine as long.
Why Do I Need To Drink Water Before A Pelvic Ultrasound
A full bladder will move the bowel out of the way and push the uterus back to better visualize the uterus, cervix, ovaries, the baby, and placental location. Ensuring that your bladder is full will help get the best images which will be used to rule out possible complications.
How much water do you really need to drink for a pelvic ultrasound?
Drink 32 ounces of water one hour before your examination time.
What happens if your bladder isnt full for ultrasound?
A full bladder in this case would not only distort the image of the uterus but it will also be uncomfortable for the woman. The bladder for this ultrasound needs to be empty. An empty or full bladder can mean the difference in how accurate the ultrasound imaging is.
What happens if you dont drink enough water before ultrasound?
Fluid can increase visibility in some cases, but it can also obstruct the view of some internal structures. There are only a few ultrasound scans that require you to have a full bladder, and your doctor will inform you when the time comes if yours should be full or empty.
What Is A Pelvic Ultrasound
Ultrasound uses a transducer that sends out ultrasound waves at a frequency too high to be heard. The ultrasound transducer is placed on the skin, and the ultrasound waves move through the body to the organs and structures within. The sound waves bounce off the organs like an echo and return to the transducer. The transducer processes the reflected waves, which are then converted by a computer into an image of the organs or tissues being examined.
The sound waves travel at different speeds depending on the type of tissue encountered – fastest through bone tissue and slowest through air. The speed at which the sound waves are returned to the transducer, as well as how much of the sound wave returns, is translated by the transducer as different types of tissue.
An ultrasound gel is placed on the transducer and the skin to allow for smooth movement of the transducer over the skin and to eliminate air between the skin and the transducer for the best sound conduction.
Another type of ultrasound is Doppler ultrasound, sometimes called a duplex study, used to show the speed and direction of blood flow in certain pelvic organs. Unlike a standard ultrasound, some sound waves during the Doppler exam are audible.
Pelvic ultrasound may be performed using one or both of 2 methods:
The type of ultrasound procedure performed depends on the reason for the ultrasound. Only one method may be used, or both methods may be needed to provide the information needed for diagnosis or treatment.

When Should You Have A Full Bladder Or Empty Bladder For An Ultrasound Scan
An ultrasound scan is done to visualize the internal structures inside the body. It makes use of high frequency sound waves to create ultrasound images of the structures in the body. Ultrasound imaging or sonography is considered to be a non-invasive procedure and does not involve ionizing radiation which is usual in X-rays. An ultrasound scan is not only useful in assessing the structure of organs and different internal structures but can also show the movement of organs in real time.
Preparing For Your Scan
Check your appointment letter for any instructions about how to prepare for your scan.
You usually need to drink about 1 litre of fluid an hour before the test, so that your bladder is comfortably full. Do not empty your bladder before the test. This is so your bladder can be seen clearly in the scan.
Take your medicines as normal unless your doctor tells you otherwise.

Do You Need A Full Bladder For An Ultrasound
Some ultrasound scans require a full bladder, while others do not. The full bladder requirement varies according to where on the body the scan is taking place and what the technologist is looking for. Here are some ultrasound scans that require a full bladder:
- Pregnancy ultrasounds in the first and second trimesters
- Renal ultrasounds, or any ultrasound of the kidney, ureters or bladder
In contrast, an empty bladder is necessary for transvaginal ultrasounds. A full bladder would obstruct the technologists view for these ultrasound scans. Ultrasound technologists also ask patients to avoid eating or drinking six hours prior to:
- Abdominal ultrasounds
- Inferior vena cava ultrasounds
- Renal artery ultrasounds
How Ultrasound Scans Work
A small device called an ultrasound probe is used, which gives off high-frequency sound waves.
You can’t hear these sound waves, but when they bounce off different parts of the body, they create “echoes” that are picked up by the probe and turned into a moving image.
This image is displayed on a monitor while the scan is carried out.

Diagnostic imaging allows doctors to observe internal structures without having to operate on the body. The advances made in imaging have been significant in aiding accurate diagnoses and treatment protocols, which is advantageous for doctors and their patients. At the same time, being the patient who needs a test such as an ultrasound, you may feel unnerved by certain guidelines. Here, we want to discuss the reasons why your doctor may advise you to arrive for your ultrasound with a full bladder.
What Are The Reasons For A Pelvic Ultrasound
Pelvic ultrasound may be used for measurement and evaluation of femalepelvic organs. Ultrasound assessment of the pelvis may include, but isnot limited to, the following:
Size, shape, and position of the uterus and ovaries
Thickness, echogenicity , and presence of fluids or masses in the endometrium, myometrium , fallopian tubes, or in or near the bladder
Length and thickness of the cervix
Changes in bladder shape
Blood flow through pelvic organs
Pelvic ultrasound can provide much information about the size,location, and structure of pelvic masses, but cannot provide a definitediagnosis of cancer or specific disease. A pelvic ultrasound may beused to diagnose and assist in the treatment of the followingconditions:
Abnormalities in the anatomic structure of the uterus, including endometrial conditions
Fibroid tumors , masses, cysts, and other types of tumors within the pelvis
Inadequate filling of bladder . A full bladder helps move the uterus up and moves the bowel away for better imaging.

What Do The Results Mean
Simple types of bladder ultrasounds, called bladder scans, can deliver immediate results. These scans are usually used only to measure the amount of urine in your bladder. A diagnostic bladder ultrasound produces more complicated images about the size, fullness, and lining of the bladder.
A doctor might understand what the ultrasound is showing, but a radiologist will typically interpret the images and write a report for your doctor to review.
The doctor will make an official diagnosis after an ultrasound based on the report from the radiologist. Apart from overactive bladder, a bladder ultrasound may also be able to help diagnose bladder cancer.
After a diagnosis, the doctor can begin treatments or therapies to help your symptoms, such as medications or pelvic floor exercises. Sometimes, more testing may be needed.
If the doctor isnt certain of your diagnosis after a bladder ultrasound, they might order other tests.
Some other tests that can be used to examine the bladder include:
- urine lab testing

Can You See Your Intestines On An Ultrasound
During the examination, an ultrasound machine sends sound waves into the abdominal area and images are recorded on a computer. The black-and-white images show the internal structures of the abdomen, such as the appendix, intestines, liver, gall bladder, pancreas, spleen, kidneys, and urinary bladder.
What Is The Purpose Of Having A Bladder Ultrasound
Many people have bladder ultrasounds in order to detect a urinary tract infection , to monitor catheters, and other bladder problems, such as difficulty urinating, urinary incontinence, and pain when urinating. It can also show the internal structure of the bladder, abnormalities, and any unusual contents of the bladder such as blockages or stones.

How You Have An Ultrasound Scan
The ultrasound scanner has a microphone that gives off sound waves. The sound waves bounce off the organs inside your body, and the microphone picks them up. The microphone links to a computer that turns the sound waves into a picture on the screen.
Ultrasound scans are completely painless. You usually have the scan in the hospital x-ray department by a sonographer. A sonographer is a trained professional who is specialised in ultrasound scanning.
The scan usually takes about 10 to 15 minutes, but it can take longer.

Full Or Empty Bladder For Transvaginal Ultrasound
I had my first ultrasound today and the technician said it was hard to see, and said that I should empty my bladder next time but I always thought you should have a full bladder???
I don’t think for transvaginal or even either for an anatomy scan, you need to have a full bladder unless your doc or the technician recommends.
they actually have me go to the bathroom prior to a transvaginal ultrasound.
Second this, even if you don’t have to go they have you try lol
My tech always advised a full bladder because it extends everything in there and makes it easier to get cervical measurements and see how everything is placed, thats how she explained it to me. But for a transvaginal my tech always let me wee first because its easier to see everything that way. Your tech really should have communicated what they wanted from you before and during your procedure.
Ugh. Well next time i will make sure to go! Urg. I was measuring 6 days behind but they saw a heartbeat! I go back in a week.
They made me pee before my transvaginal, and during my anatomy scan the ultrasound tech let me get up and pee in the middle of it because she could see the fluid in my bladder. I didnt even know I had to pee but she was right she said it was for my comfort, and also my baby wasnt moving around much and we needed him to flip, and she thought maybe if I gave him some more room it would help.
How Is An Abdominal Ultrasound Done
For an abdominal ultrasound scan, you lie on your back on a comfortable table. You will need to pull up or remove your shirt or put on a hospital gown.
During the test, a trained professional:
- Applies gel to your abdomen: Water-soluble gel will cover any areas on your belly that the provider will examine. This gel may feel cold. It will not hurt you or damage your clothes.
- Moves the probe over your skin: The technician gently moves the handheld ultrasound wand over your skin, on top of the gel. The technician moves the probe back and forth until they clearly see the areas in question.
- Gives you instructions: The professional performing this test has received training in how to achieve the clearest images. They may ask you to turn to one side or hold your breath for a few seconds.
- Cleans your skin: The technician wipes off any remaining gel on your skin.
If your provider wants to study your blood vessels, your test may include Doppler ultrasound. Doppler sound waves detect details of how blood flows inside your blood vessels.

Full Or Empty Bladder Ultrasound Scans:
- Pregnancy Ultrasound If the pregnancy is in the early stages, before the 20th to 24th week, then it is necessary to have a full bladder for an ultrasound. This is needed to provide better visualization of the pelvic organs. In the later stages of pregnancy, the fetus moves from the pelvis and is surrounded by amniotic fluid, which serves as a medium for visualization, and its no longer necessary to have a full bladder. In fact, in this case, a full bladder may distort the imaging.
- KUB Ultrasound KUB is used to evaluate the urinary tract, including the kidneys, urinary bladder . KUB ultrasound is used to observe if there are changes in the kidneys that can point to signs of damage, structural abnormalities, and even the presence of kidney stones, tumors, or cysts. Patient must often drink a liter of water one hour before the ultrasound is performed. In this case, the full bladder is necessary to evaluate the urinary bladder properly as the bladder volume will be measured during the scan.
- An empty or full bladder can mean the difference in how accurate the ultrasound imaging is. Knowing what imaging procedure you are scheduled for can determine whether or not you need to have an empty or full bladder.
The Ultrasound Bladder Prep
The dreaded bladder prep may vary a little from one place to the next, but goes something like this:
- Empty your bladder 1.5 hours prior to your exam
- Drink 32ozs of fluid within 30 minutes
- Have all fluid down 1 hour prior to your exam
- Do not pee until exam is complete!
To clarify, lets say your appointment is 10am. You will pee at 8:30am, drink from 8:30 to 9am, and have all the water down by 9. Most bladders require the full hour to fill completely. Do not pee before your appointment time! This action, of course, defeats the whole purpose for drinking, but you would be suprised at how many do.
Will you feel like you have to pee before this hour is up? Oh, yes maam! Not many people allow their bladders to fill to this capacity before they feel the urge to tinkle. It might very well feel like the L O N G E S T hour of your life.
Dont even look at one of these:
Or listen to this:
And youll definitely want to steer clear of one of these:
I promise. You wont be happy if you dont!
There is a bit of good news to all this. Once full, the exam is pretty quick . . . 5-10 minutes in most easy-to-see negative cases.
How To Prepare For A Bladder Ultrasound
A bladder ultrasound requires a full bladder. With that in mind, here are some steps to take in preparation for your bladder ultrasound:
- Empty your bladder one to two hours before the ultrasound.
- Drink one liter or 32 ounces of water 30 minutes before your ultrasound appointment. Dont empty your bladder again until the appointment ends.
- Wear comfortable clothing and take any prescribed medication as directed.
- Arrive at the ultrasound clinic 15 minutes before your appointment.
You can also eat as you usually would on the day of your ultrasound appointment. For individuals with a bladder catheter, you can clamp the catheter one to two hours before the appointment.
Should We Eat Before Ultrasound
You may not eat or drink anything for 8 to 10 hours before the test. If you eat, the gallbladder and ducts will empty to help digest food and will not be easily seen during the test. If your test is scheduled in the morning, we suggest that you eat nothing after midnight the night before the test is scheduled.
